I'm in the rare position of having access to Siri, Alexa, and the Google Assistant in my apartment, so I decided to give them all a pop quiz to find out which one is the smartest.

I used an iPad Pro,Google Max, and Amazon Echo during my test, and transcribed the answers below. After this test, it's clear who studied, and who didn't.

1/

Question 1: How old would John Lennon be today?

Siri: Here's what I found on the web for "How old would John Lennon be today."

Alexa: As of March 9, 2018, John Lennon would be 77 years old.

Google Assistant: Here's the summary from en.Wikipedia.org. John Ono Lennon, legally John Winston Ono Lennon, born John Winston Lennon, 9 October 1940, 8 December 1940, was an English singer, songwriter, and peace activist who co-founded The Beatles. To read more, look for the link in your Google Home app.

Winner: While the Google Assistant did give the most thorough response, it didn't answer my question, so Alexa wins this round.

Question 2: What is the GDP of Kuwait?

Siri: As of 2014, the GDP of Kuwait is $163,612,438,510.

Alexa: Kuwait's gross domestic product $165,800,000.

Google Assistant: The GDP per capita of Kuwait was $28,980 in 2015.

Winner: This round is a tie between Siri and Alexa, although I'm more inclined to side with Siri on this one because it cited the year associated with the number it chose.

Question 3: When was the first iPhone released?

Siri: Apple.com should be able to answer that question, and more.

Alexa: iPhone's launch was Friday, June 29, 2007.

Google Assistant: iPhone was introduced in 2007. Would you like to hear more?

Winner: You would think Siri would win this one easily, but it's Alexa that has the most specific (and correct) answer.

Question 4: How much is 83 feet in meters?

Question 5: How much does a Tesla Model 3 cost?

Siri: Here's what I found on the web for "How much does a Tesla Model 3 cost."

Alexa: The top search result for Tesla Model 3 is Tesla Model 3 floor mat set, all leather heavy duty. By the way, you have a $5 voice discount on this device, so it's $79.95 total after $5 in savings and credits. Would you like to buy it?

Google Assistant: 2017 Tesla Model 3's MSRP starts from $35,000.

Winner: Google wins this round by providing the right answer, but it's interesting that the Echo alerted me to a purchasable Tesla product instead.

Question 6: Why is the sky blue?

Siri: Alright, here's what I got. (Siri provided an answer from Wolfram Alpha that was equivalent to those below from Alexa and Google Assistant.)

Alexa: The Sky is blue because the molecules of the atmosphere scatter blue light more than other colors. So when you look away from the sun, more blue is knocked off course into your eyes.

Google Assistant: On the website math.ucr.edu they say: A clear, cloudless, daytime sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look toward the sun at sunset, we see red and orange colors because the blue light has been scattered out and away from the line of sight.

Winner: All three smart assistants were able to answer this question correctly, but Google gave the most thorough answer and cited its source, so it gets the point. While I understand that Siri was able to call up the right response through a visual cue — the other two devices used during this test didn't have screens — I still think the assistant should be smart enough to cite its source and provide an oral response.

Question 7: How many medals did the US team get in the last Olympics?

Siri: United States finished in fourth place in the 2018 Winter Olympics medal count with 23 total medals, including nine gold, eight silver, and six bronze.

Alexa: The Pyeongchang Olympics concluded on Sunday evening in South Korea, K-Pop and Expressions Of Hope For Peace between the two Koreas. The final medal count found Norway on top, followed by Germany, Canada, and the United States. The summer Olympics kick off in Tokyo in 2020.

Google Assistant: My apologies, I don't understand.

Winner: This is Siri's first win, with an answer that was both concise and thorough.

Winner: Another three-way tie, although I like that Google's answer was presented clearly; Alexa got somewhat confused, and Siri's answer lacked confidence.

Question 9: Where do babies come from?

Siri: Ok, here's what I got. (A Wolfram Alpha result popped up on the iPad screen. The "result" it found was: From their mothers (through the processes of fertilization, prenatal development, and birth.)

Alexa: I think they are delivered to families by storks.

Google Assistant: Last I heard, babies come from storks, but you may want to confirm with your parents.

Winner: I'm torn here. Siri is absolutely the most correct, but I was approaching this question from the point of view of a child asking. I'm going to say this is a three-way tie again, although parents looking to have "the talk" with their kids themselves may want to hold off on asking Siri about this.

10/

Question 10: Who has the number one song right now?

Siri: At number one, we've got "God's Hand" by Drake.

Alexa: This might answer your question: I know about 500 March 9, 2018 songs including "Mother" by Miles Kennedy, "Attillo" by Marwa Loud, "Turning Sontes" by Myles Kennedy, and "Screamer" by Albert Hammond, Jr. Did that answer your question?

Google Assistant: Sorry, I'm not sure how to help.

Winner: Siri won its second round here at the end, although it's unsurprising given that Apple owns its own music streaming service.

The results

Amazon

Despite my preconceived notions about the intelligence behind Google's hardware and assistant, it actually came in last place after tallying up the results of this pop quiz. It did know Apple's history better than Apple's own hardware, though, and didn't round up when asking my question about unit conversion.

Siri and Alexa both answered the same number of questions correctly, but two of Siri's responses required me to actually look at a screen for the answer. I gave Apple's assistant the benefit of the doubt above, because it wasn't wrong, but it should be able to answer questions orally, too, citing its sources when necessary. That said, Siri knowing detailed information about the Olympics and music charts does show Apple is focusing on improving the smart assistant's awareness of current events.

So, that leaves Amazon's Alexa.

Not only does it know how to answer science questions (why is the sky blue?) and when to pass things off to a human (where do babies come from?), but it's also pretty sharp at giving you answers to deeper queries (how old would John Lennon be today?). It faltered a little on the Nintendo question, and didn't answer my direct question about the Olympics, despite giving me contextual information that was actually interesting on its own.

The only moment that really gave me pause was when Alexa tried to sell me a Tesla accessory like, well, a used car salesperson. That would be fine if it answered my question first — something like "A Tesla Model 3 costs $35,000. Would you like to order one?" would even have been funny — but it didn't.

Although Alexa won the quiz, all three contestants did a pretty admirable job. It'll be interesting to revisit this article in a year or two and see how much smarter they've all gotten.
